What Is a Nutrient Management Plan?
A Nutrient Management Plan (NMP) is a regulatory document under Ontario's Nutrient Management Act that focuses on how nutrients are applied to agricultural land. It covers manure application rates, timing, setbacks, and soil testing requirements.
Farms that exceed 300 nutrient units typically require an NMP in addition to an NMS.
When Do You Need an NMP?
Your farm exceeds 300 nutrient units
You are applying nutrients to agricultural land from a large operation
Your operation requires both an NMS and NMP under O. Reg. 267/03
You receive nutrients from off-farm sources

Frequently Asked Questions
Do I need an NMS to build a barn in Ontario? In most cases, yes — if you are increasing livestock or nutrient storage capacity, you will likely need a Nutrient Management Strategy (NMS) before construction can begin.
What are nutrient units? A nutrient unit is a measurement used under Ontario's Nutrient Management Act to determine the regulatory requirements for your farm. It's based on the type and number of livestock you have.
When do I need both an NMS and an NMP? Typically when your farm operation exceeds 300 nutrient units, you'll need both a Nutrient Management Strategy (NMS) for storage and expansion, and a Nutrient Management Plan (NMP) for land application of nutrients.
How long does approval take? Approval timelines vary depending on the complexity of your operation. Most plans take several weeks from farm visit to final approval. Starting early is critical — delays can cost you a full growing season.
